ATTORNEY v Patented Nov. 11, 1941 UNITED STATES PATENT; OFFICE rt 2,262,601 v BOOK Arthur F. Brook, Madison, N. J. Application June 6, 1941, Serial No. 396,789

6 Claims.

.The invention herein disclosed relates particularly to books of the mechanically bound type, in which the leaves are held in a mechanical form of binding, usually of wire, sheet metal or plastic. Such bindings have complete reversibility and free swinging of the leaves over from one side to the other.

Important objects of the present invention are to provide a cover construction for bindings of the type mentioned and simple and inexpensive means for securing the bound leaves in the cover and which while holding, the leaves properly centered, will not interfere at all in the free swinging and reversing movements of the leaves.

Also it is a purpose of the invention to secure the bound sheets in place in a manner that will not add to the bulk of the book or interfere with the flexibility of the covers or the bound sheets, which willtbe unobstrusive and practically invisible in the ordinary use of the book and which will provide a particularly practical and effective construction for books of the refillable type.

Other desirable objects and the novel features by which purposes of the invention are attained will be in part apparent from or are set forth in detail in the course of the following specification;

The drawing accompanying and forming part of the specification illustrates simple commercial embodiments of the invention. Structure however may be modified and changed as regards this disclosure all within the true intent and broad scope of the invention as hereinafter defined and claimed.

Fig, l is a broken plan view showing the invention applied to a book of the refill type, the book appearing in open position with the sheets all turned over on the front cover.

Fig. 2 is an enlarged broken sectional detail as on line 2-2 of Fig. 1.

Fig. 3 is an end view of cover closed position.

the book with the the advantage of Fig. 4 is a broken detail illustrating a simple way of engaging a refill in or removing it from the cover.

Fig. 5 is a broken detail view of a modification.

The invention is particularly adapted to and is here illustrated in conjunction with a binding of the Wire-O type, in which the sheets 5, perforated at 6, are held by a single continuous wire, bent in zig-zag fashion into the form of doubled hooks or rings 1, connected at the back in spaced parallel relationship by short straight intermediate connecting portions 8.

A special feature of the present invention is the utilization of these short flexibly related,

longitudinally extending back connections as a part of the means for retaining the binding in the cover structure.

In the illustration, the cover is made up of front and back cover sections 9, l0, flexibly connected by a back portion I I.

Mounted on the back ll, between the cover hinging edges I2, l3, are two or more transversely extending retaining hooks l4, spaced to engage over two or more of the longitudinally extending back connectionsB, of the binding.

In the present illustration, two such transversely extending retainers are provided, one near the top and the other near the bottom of the back and spaced to engage the sides of the adjoining rings at l5, thus to hold the binder snugly against longitudinal shifting movement in the cover.

In a preferred form of construction, the retainers M, are formed as projecting spring tongues struck up from the edge portions of tubular rivets l6, set in the back, said spring tongues having at the base of the same substantially circular wire clasping portions II, approximately at the edges of the eyelets and extending inward toward or into the tubular structure of the eyelets at l8, and terminating in outwardly inclined cam portions IS,

The rounded portions II, at the root ends of the holding tongues may be only slightly larger than the cross-section of the wire, so as to form loose bearings for the back connections 8, the inwardly extending portions l8, serve as retaining means to hold the back connections in such bearings and the outwardly inclined tips l9, may be used as cams to lift the spring tongues under pressure of the back connections when entering the binder'in the cover. In similar manner, the inwardly inclined. portions of the tongues adjoining the moreor less circular retainer portions may serve as cams to force the spring tongues open, in releasing a binding from the cover.

The eyelet or rivet form of base structure for the spring holding tongues takes up little space retainers in placing or removing the refills and, as shown in Fig. 4, the parts may be engaged or disengaged one at a time. Thus in the view referred to, the connection portion of the binder has been engaged or is still engaged with the retainer at the top, while the connecting portion at the bottom has been released from or is not yet engaged with the lower retainer, the binding being at an inclined relation, hinging on the top retainer to swing it into or free it from engagement with the other retainer.

While retainers at the top and bottom usually 7 are sufiicient, for longer books, one or more inter.

mediate retainers may be provided, it only being' necessary that these be located so as to catch one or more of the longitudinal portions connecting the rings in the intermediate binding.

. The connecting portions form in efiect a flexible-backbone and the engagement of the re tainers with these flexibly joined back connections does not destroy or impair the desired flexible character of the binding or cover structure. The end retainers by engagement with the inner sides of the end hooks or ringsihold the binding in its normal longitudinally distended condition. The engagement and disengagement is effected by a short substantially transverse relative movementof the parts, which requires no bending or mis-shaping of either the binding, the sheets or the cover structure. 1

While the invention isof particular value as a refillable book construction, it is realized that 'the' hooks or holding tongues may be wholly or permanentlyclosed about the back connections 3. In a book construction for perforated sheets bound together by spaced substantially parallel transverse rings connected in such spaced relation by short intermediate longitudinally extending section of the of the. binding, thus to permanently secure the- I bound sheets within the cover structure. It is realized also thatthe binder rings may not be entirely closed, thus to leave the sheets in a removable and replaceable relation, held for ex ample, by special retaining means, such as covered in patent application February 19, 1941.

Fig. 5 shows how the retainers may be madewith the retaining loops or bearings Ila, located substantially centrally over the eyelet bases, thus to hold the binding at all times substantially at the center of the book, directly over the rivets. In this, as in the first form of construction, the

transversely extending spring tongue has an -upwardly or outwardly inclined cam portion I So,

for Wedging engagement by a connecting bar 8,

and a downwardly or inwardly inclined cam portion Isa; for facilitating the releasing action of the spring holding tongue.
